Quoted from Gizmata:I did, and traced it to the 4 pin connector leaving the metal box where the yellow wire (12v) pin "wings" were bent wrong so it was not staying seated in the connector. I bent the wing back, but it still doesn't stay seated. I think it stripped the plastic on the connector as well.
added: The pin seems to stay in for now, but I expect vibration to have it come loose eventually.
Yes, I don't think I have a problem with the connector staying seated, but it does seem like where the plastic bracket holding the pins on the board in the monitor has some play in it. I don't think my problem is the same, because when I disconnect everything and just plug the power back in to the monitor, I get a blue screen briefly and then it goes dark, so similar to a computer monitor getting no input but is getting power. I mentioned before if I connect the VGA as well and pull the cables upward it seems to work, but when I mount it back on the game the monitor goes dark, sometimes displays but is dim, and rarely it works. Almost like there is some kink in the VGA cable that connects periodically from vibration. Like you mention, if the pops fire, the shaker comes on, or the VUK in the right scoop/hole fires it flickers. So I have to get back in there, when I find time because I'm dying to see the timer on there when I start modes!
